Linkoeping

The city is possibly named after the Lionga ting assembly which according to Medieval Scandinavian laws was the most important thing in Östergötland. Exact location of the Lionga ting is not known, but it was along the Eriksgata. The term "-köping" means there was a market there. Historically, Linköping is famed for being an early diocese, c. 1082, second in Sweden (within its pre-1658 boundaries) only to Skara. The diocese is first mentioned in 1104 in the so-called "List of Florence" (Lionga. Kaupinga). The monastery of Vreta Kloster near Roxen north of Linköping was established in 1128, and the oldest parts of the cathedral are also from the 12th century (although it has been changed many times since then, the eye-catching tower with copper roofing being a 19th-century product). …

Linköping has a humid continental climate (Dfb), though with maritime influences, retaining the large differences between seasons but being comparatively mild when measured against other areas of the world on similar latitudes. Linköping tends to be slightly cooler in summer than nearby areas in the Mälar valley, but still was the weather station in Sweden among the officially listed for monthly statistics, that until 2018 had come the closest to a subtropical month, with July 1914 having a mean temperature of 21.8 °C (71.2 °F), with the subtropical border being at 22 °C (72 °F) for the warmest month. Normally summer highs average in the low 20s and winter temperatures commonly hover just above the freezing point during the day, then falls below it at night.

Linköping offers a wealth of leisure activities to people of all ages. Residents and visitors are able to enjoy art, theatre, history, concerts, markets, festivals and sporting events. Special sights of interests are: the locks of Berg on the Göta Canal, the locks of the Kinda Canal, Gamla Linköping, Valla skogen and Valla fritidsområde (Old Linköping, Valla Wood, and the Valla recreational area), Flygvapen museum (the Air Force Museum), Linköping's domkyrka (the cathedral), Slotts- och domkyrkomuseet (the Castle and Cathedral Museum) and Östergötlands Länsmuseum (the Östergötland County Museum). Konsthallen Passagen is an art gallery located in the main square. Tornby, to the north of the city centre, is a shopping area with retail outlets. The city and its environs offer all sorts of green landscapes to see and experience. …

One of the biggest employers in Linköping is Saab which among other products manufactures the SAAB Gripen fighter jet and where the SAAB 340 twin-engine commuter turboprop was produced at Linköping/Saab Airport, which is why it is called "The flight city". The city also has a strong presence in information technology with the headquarters of IFS AB, Sectra AB and Cambio Healthcare Systems AB, as well as the presence of Motorola, Ericsson, Infor, and many others. Toyota Industries Sweden AB has a presence in Linköping, as one of its subsidiaries, BT Industries, is located in nearby Mjölby.

The city is situated south of lake Roxen (which is part of the historically important water paths Motala ström and the Göta Canal) where the E4, Sweden's highway backbone, crosses the river Stångån (and Kinda kanal). It is situated on the main southern railway line connecting Stockholm with Malmö and Danish capital Copenhagen. Linköping/Saab Airport offers daily connections to Amsterdam. In 2019, the city started experimenting with two autonomous buses that run along a 2 km route around the university campus.
